Thank you for informing this.

Let me add this series to my list first. The feature freeze date is
Fri Sep 2, 2022 and code freeze date is Fri Sep 23, 2022. My personal
feeling would be as long as (1) this series can get a good shape to go in
before the code freeze and (2) other x86 maintainers don't have
objection to accept this series, it is fine with me. Also if x86 people want
this series in the release and it won't cause the delay of release, I don't
think there would be any reason to refuse this series :))) So I guess please
just keep these 3 patches for now and let's see what the discussion in
this series will be.

Kind regards,
Henry
